Abstract

A magnifying device includes a translucent member having a first portion of a predetermined size and having a first end having a predetermined convex shaped surface and second end defining a surface portion, a second portion of a predetermined size and having a diameter substantially equivalent in diameter to the second end of the first portion and having a first end generally defining a surface portion concentrically integrally formed adjacent with the second end of the first portion and having second end defining a surface portion, a third portion of a predetermined size having a first end generally defining a surface portion integrally formed adjacent with the second end of the second portion and having a second end of a predetermined smaller diameter than the first end of the third portion and defining a generally planar surface portion, wherein an angle is formed between the second end of the first portion and the second end of the third portion such that when viewing from the first end of the first portion through to the second end of the third portion a substantially magnified focused region is formed substantially at the second end of the third portion by virtue of the predetermined sizes.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A magnifying device, which includes: a first translucent portion of a predetermined size which includes a first end defining predetermined arcuate shaped surface, a second end defining a surface portion, a first side and a second side interconnecting said first end and said second end;   a translucent second portion of a predetermined size and having a diameter substantially equal in diameter to said second end of said first portion and having a first end defining a surface portion integrally formed adjacent with said second end of said first portion and having second end defining a surface portion, and further having a four sides interconnecting said first end and said second end of said second portion; and   a third translucent portion of a predetermined size having a first end generally defining a surface portion integrally formed adjacent with said second end of said second portion and having a second end of a predetermined smaller diameter than said second end of said second portion and defining a generally planar base surface portion, and further having a four sides interconnecting said first end and said second end of said third portion, wherein an angle is formed between said second end of said first portion and said second end of said third portion such that when viewing from said first end of said first portion through to said second end of said third portion a substantially magnified focused region is formed substantially at said planar base surface portion of said second end of said third portion.   
     
     
       2. The magnifying device of claim 1, which further includes a magnetic portion connected to said device in a nonobstructing manner with respect to said focused region. 
     
     
       3. The magnifying device of claim 2, wherein said magnetic portion has a printed surface thereon which is readily viewable. 
     
     
       4. The magnifying device of claim 2, wherein said magnetic portion is disposed adjacent and between said ends of said third portion. 
     
     
       5. The magnifying device of claim 1, wherein said a focal length exists between substantially any given point on said first end and any given point on said planar base surface portion. 
     
     
       6. The magnifying device of claim 1, wherein said base surface portion has a relatively thin reference line transversely extending thereacross to aid in the viewing of text. 
     
     
       7. A magnifying device, which includes: a first translucent portion of a predetermined size which includes a first end defining a predetermined arcuate shaped polygonal surface portion, a second end defining a polygonal surface portion, a first side and a second side, a first side and a second side interconnecting said first end and said second end;   a translucent second portion of a predetermined size and having a diameter substantially equal in diameter to said second end of said first portion and having a first end defining a defining a polygonal surface portion and which is integrally formed adjacent with said second end of said first portion and having second end defining a generally rectangular surface portion, and further having a four sides interconnecting said first end and said second end of said second portion; and   a third translucent portion of a predetermined size having a first end generally defining a rectangular surface portion integrally formed adjacent with said second end of said second portion and having a second end of a predetermined smaller diameter than said second end of said second portion and defining a generally rectangular planar base surface portion, and further having a four sides interconnecting said first end and said second end of said third portion, wherein a tapered angle is formed between said second end of said first portion and said second end of said third portion such that when viewing from said first end of said first portion through to said second end of said third portion a substantially magnified focused region is formed substantially at said rectangular planar base surface portion of said second end of said third portion.   
     
     
       8. The magnifying device of claim 7, which further includes a magnetic portion connected to said device in a nonobstructing manner with respect to said focused region. 
     
     
       9. The magnifying device of claim 8, wherein said magnetic portion has a printed surface thereon which is readily viewable. 
     
     
       10. The magnifying device of claim 8, wherein said magnetic portion is disposed adjacent and between said ends of said third portion. 
     
     
       11. The magnifying device of claim 7, wherein said a focal length exists between substantially any given point on said first end and any given point on said rectangular planar base surface portion. 
     
     
       12. The magnifying device of claim 7, wherein said base surface portion has a relatively thin reference line transversely extending thereacross to aid in the viewing of text.
